Walking on Eggshells
This person purchased way more empty plastic eggshells than they had planned. They weren’t sure if they even received said empty plastic eggshells to begin with. If you look at the image below, you’ll see that they resemble adult items. You’re probably thinking of it.
Yes, those are the ones. Someone is going to have a wonderful Easter! If this individual wanted to, they could sell the eggshells just as they appear in the picture above. Make individuals believe they’re something else by making them think they’re made of gold. Turn a profit without being a deceptive little weasel and fill them with sweets and chocolates for the children.
